main board
 

does any one have a diagram of the manin board i have oine that is screwed and i need to figure out where to hook things up

i will also take pics of the bottom of the board where the battery wires connect

BC posted one a while back in one of my threads i cant find the thread though. ill see if i can find the pic for you.

thanks i will keep mjy eyes open now that i now where to look

are there any electronics pout there that will fit in a xmod with little or no moding that are cheap ? or should i just try to get anpother board if i cant fix the one i have

Go to www.atomicmods.com. Rob has alot of pictures of the board. If you look around, you might even find a drawn out schematic of the board. What part of the board are you interested in? The ESC?

Here's a schematic of the stock ESC. This, folks, is what an h-bridge is.

This schematic is true to the parts references on the xmod board. The DC voltage sources are replicating the pins of IC1. I did this to simulate the circuit and test its functionality. The box looking thing in the middle "xmm 1" is a multimeter. I used it to replicate a motor to test the changing states of the voltages and currents. This is your ESC.

I have a design of my own that should be able to handle 20x's the power as any h-bridge possible could with the small 8 pin IC's. I'm going to use TO-220 power FET's and restructure the circuit a little to make for better FET driving. There has to be a level shift between the weak 0V to 3.5V PWM signal and 16V+ DC. So you need to encorporate driver transistors to help fully turn the power FET's on and off, with a little help from the very power that they are switching on and off to the motor. A little pre-amplification, if you will.

i found it. i dont know if it is it though. if you need it just tell me.

ok heres a pic of my main board from when i couldnt soder and i was replaing the battery wires. it wasnt smart but i hope it can be fixed the board isnt fried i jusr dont no where to connect cause some of the connections are gone and what not.

if u no where to connect can u use ps or paint to show where to connect every thing

Here you go, man. Hope this helps.

thanks
that might help i will work on it when i get some more suplys
